![]() ![]() Most eel species are nocturnal, and thus are rarely seen. Most eels live in the shallow waters of the ocean and burrow into sand, mud, or amongst rocks. They can swim backward by reversing the direction of the wave. Eels swim by generating waves that travel the length of their bodies. The dorsal and anal fins are fused with the caudal fin, forming a single ribbon running along much of the length of the animal. They possess no pelvic fins, and many species also lack pectoral fins. Adults range in weight from 30 g (1 oz) to well over 25 kg (55 lb).
